ELECTRIC BATTERY.

The object ,of this-present invention is .to

provide an ,electric battery in which the switch is located entirely within a box inclosing the battery cells so that current may be cut off 'from the terminals on the exterior of the box when so desired, for preventino' an external connection between the poles ofa the battery when the switch is off.

A further. object is to provide a Water tight box;` for'inclosing the cells and switch. A still''fu-rt'her object is to ropvide a simple and ,elfefe'tive means for rin ing additional cells of a battery successively into the battery circuit 5 y In the* accompanying drawings, Figure 1 represents my improved electric battery in top plan, Fig. 2 is a vertical transverse section through the battery taken in the lane of the linel A-A of Fig. l, Fig. 3 Vis av orizontal section taken in the plane of the line B-B of Fig. 2, Fig. 4 isa horizontal section taken in the plane ofv the line C-C of Fig. 2, Fig. 5 is a diagrammatic view showing the electrical connections, Fig. 6 is a deta1 plan View showing the positions whichy the parts assume when circuit is broken at the switch, and Fig. 7 is a detail side View of one of the battery contacts.

The eight battery cells are herein denoted h by the numerals 1 2, 3, 4, 5,6, 7 and 8. The

cells are connected in series as usual.

A battery box is provided for the cells, which box 1s .denoted by 9. This box has a top 10 .and a horizontal partition 11 located within the box `ust above 'the tops of the battery cells.' T is box is made liquid tight so as to prevent the admission of moisture to the interior of the same and the cells herein represented are of the well known dry c'ell type.y

The switch for the battery is locatedv entirely within the box, in the present instance in the space between the top or cover 10 of A the boxand the partition 11. This is constructed,' arranged and o ratedas follows A vertical shaft 12 1s mounted 4in a acked bearing 13 in the top 10 of the box or preventing the admission of moisture to the interior ,of the box. This shaft'- 12 is Specieatian ot Letters latent. Application ined xml; s, isos. serial 110.243,413.

ing handle 14.

provided exterior to the box with an operat- I Within the boxthe Shaft 12 hasaxed" thereto adjacent to the partition 11, a contactl plate 15, which forms the rotary contact of the switch. This contact late 15 is provided on its peri hery with a ug 16 arranged to be broug t successively into en# gagementwlththe battery contacts to be4 herein described. This handle shaft 12 .is further provided with a disk 17 of insulating material, such, for instance, as fiber, the periphery of which disk is provided with a recess 18.

An auxiliary circuit maker and breaker is Ylocated in the battery circuit, which circuit maker and breaker comprises arms 19 and 20 located in the space between the top and partition of the box. This arm 20 is held pressed against `the arm 19 because of its en agement with the periphery of the insu atlng disk 17. 1

When the disk is rotated to brin the recess 18 opposite the arm 20, it wil v.permit the arm to spring back away from its contact with the armr19.

Battery terminals 21, 22, are mounted on the exterior of the battery box. TheY terminal 22 is connected throu h a wire 23 Within the box to the arm 1 9 .o the circuit maker and breaker. The arm 20 of the circuit maker andmbreaker is connected by a wire 24 with the -l-side ofthe battery cell 1. The terminal 21 is connected by a wire25 within the box to a spring contact 2 6 which is at all times in engagement with the rotary contact 15.

A series of springk actuated battery con` tacts are located in position to be .successively engaged by the lug 16 of the rotary contact. In' the present instance I have shown five of these battery conta-cts denoted,

respectively, by 27, 28, 29, 30 and 31. These contacts are connected through Wires 32, 33,

V34, 35, and 36, to the sides'of the battery cells 4 to 8 inclusive.

As thecontact 15 is rotated'by the handle l 14 it will successively brin into the battery circuit the cells 5, 6, 7 an 8, as desired to ,re ,lenish the electric current.

and the lug 16 of the disk,. 15 out ofenga'ge-vl y y, hen it isdesired to break the current,' `ltl'ie handle 14 is turned to bring the parts nient with all vof the battery contacts. This will permit the arm 20 to be released from its engagement with the arm 19 thereby cutting ott' the terminal 22 Within the box. The

terminal 21 is also cut off because of the position which the lug 16 of the disk 15 assumes. It `will thus be seen that the'electric circuit is cut oi from Within the'box from both of the terminals 21, 22, doubly insuring the prevention of a brid being formed bef tween the terminals or tvveen one ofthe terminals and a part of the box.

The handle shaft 12 may be provided exterior to the box with a pointer 37`-Which may be used in connection with an index on the top of the box for indicating Whether the circuit Within the box 4is broken and for indicating the number of cells which are in the battery circuit.

It is evident that this device may be used in connection With batteries having a greater or lesser number of cells than that herein represented, the particular number shown being chosen to give a clear understanding of the invention.

What I claim is l. In :an electric battery, a lurality of cells, a box nclosing the same, attery terminals, a switch located within the .box arranged to cut off one of the battery termi-v nals, an auxiliary circuit maker and breaker under the control of the switch for cutting off the other battery terminal and ,means exterior to the box for operating the switch.'

2. In an electric battery, a plurality of cells, a box inclosing the same, battery terminals, a switch located within the box arranged to cut off one of the battery terminals and to successively bring additional cells into the battery circuit, an auxiliary circuit maker and breaker-under the control of the switch for cutting off the other battery terminal and means exterior to the box for operating the switch.

In testimony, that I claim the foregoing as my invention, I have signed my name in presence of two Witnesses, this 28th day of February, 1905.
